Test Flanges are blind flanges with a drilled and tapped NPT (threaded port connection).

With our full-service machine shop, we typically drill/tap these flanges with ½”, ¾” 1”, 1-1/2”, and 2” NPT, in either off-set (fill / drain) or center locations.

Our test flanges are in stock and readily available for rental in A105 material grade and available in all sizes ranging from ½” to 60” in both raised face (RF) and ring type joint (RTJ) finishes.  Sizes greater than 24” are also available in both Series A and Series B.

Rental options are guaranteed to be without flaw for the intended application, are blasted/primed with a Dimetcote® coating (for rust and weather resistance), and color-coded by class rating and stamped stenciled for easy identification. Items weighing greater than 50 lbs. will have a lifting lug along the OD for shackle lifting and simplified installation.

If longer lead times are allowed, purchase options are also available in all sizes, material grades, and finishes.  When competitor lead times are too long, we pride ourselves in our ability to manufacture any size blind flange in-house with our machine shop capabilities.
